Re: [Discuss-gnuradio] Question about sampling rate

Hi...I mean... the sampling rate of the uhd sink and source what refers to...? I've since in some documents that if you are transmitting , you have to take in account that the DAC for output works at 128 M/s and the sample rate for the UHD sink block has to be determined somewhow from that.

In the same way the ADC for reception works at 64 M/s and the sampling rate for the UHD source block has to be determined somehow from that 64 M/s .

I just want to make simple transmission and reception.

Am I wrong? or I am understanding not really good what I am reading about this. Thanks in advance.

Don't worry about the USRP native rate (64/128Msps). The FPGA inside the USRP handles interpolation and decimation to step from the sample rate of the USB interface (0.5Msps to 8Msps) to the ADC/DAC rate (64Msps/128Msps). The sample rate you choose should be the sample rate that is appropriate for your application.
